Iga is situated almost at the midpoint between Osaka and Nagoya. It is a castle town completely surrounded by mountains. The city is laid out in a neat grid of streets. It is famous as the birthplace of the Iga ninja spies. Iga is also noted as the birth place of the haiku poet Matsuo Basho, who created 'haiku,' unique Japanese-style short poetry consisting of 3 lines with 17 syllables. The ninjas would infiltrate into the enemy's ground with their special skills called 'ninjutsu,' with the objectives of scouting, conniving stratagems, raiding, harassing the rear guard and engaging other activities. Two of Iga's main tourist attractions are the Iga Ueno Castle and the Iga-ryu Ninja Museum, the area around the city being the historical home of the famous Iga Ninja. Iga Ueno Castle is famous for having the highest stone walls in Japan. At the Iga Ninja Museum, you can enjoy watching powerful ninja shows, and experience for yourself the challenge of throwing ninja stars and even try on real ninja clothing. There is annual Iga Ueno Ninja Festa ninja festival in every spring.
